USSR childhood began from #51. That’s because “Turbo” bubble gums were massively delivered with wrappers of 2nd series (#51-#120). Almost anybody hadn’t seen wrappers of 1st series. The counted number of these papersheets was ocasionally brought through the Iron Curtain by Soviet sailors. They disorientated even more and as the result 1-50 wrappers were covered by myths & legends, remaining undiscovered until beginning of Interner era.
